FIELD OF THE INVENTION

The present invention refers to structures for the exhibition ofproducts, and more specifically to exhibiting shelves that are easilytransformable in order to exhibit products in a point of sale, and evenmore specifically to showcases of products with at least one shelf orrack used to hold up or bear and exhibit products in a point of sale anda method for the assembly, disassembly and transformation of theseshowcases.

BACKGROUND OF THE INVENTION

The constant growth of population demands a production in great volumesof products to be purchased. At the points of sale, structures that canbear a great volume of products in small spaces are required, withoutloosing the essential detail of exhibiting the product. The distributorsof consumable products often have a problem with regard to how to set upthe product on a showcase, in a quick and complete manner, in the lesstime possible, and at the same time having a showcase that issufficiently capable of bearing these consumable products while beingexhibited.

The producers try to solve these problems sending the products packed ina structure that can transport and exhibit the products at the sametime. While this is useful for certain kinds of products, there areother products that have to be set up in situ due to the kind of productor because the producers prefer it this way.

These showcases are known in the art. An example is the publication No.CN 2657476, where a collapsible tripod for racks is released, whichcontains sheets at the left and right sides provided with holes fortheir connection.

The publication JP 2004045577 reveals a display panel that is easy toassemble, collapsible into a compact unit and designed to hide atransversal section and a connection face.

The French Patent No. 2 795 217 reveals a freight showcase that isself-standing, that has a frame and support sections, and is connectedby a strip and separated by folding lines. The frame is prismatic andthe support sections are formed internally. Springs provide an automaticassembly of the frame.

The British Patent No. 1 463 899 reveals a frame of showcase that has abody defined by triangular or rectangular sheets, each rectangular sheethas a plastic body and it has racks that sustain articles, and thetriangular sheets have fold lines perpendicular to the bases. The sheetsare preferably made of cardboard, the fold lines allow the collapsing ofthe showcase for its transportation, and the bodies are vacuum moldedfrom strips made of plastics.

The British Patent No. 2 122 479 reveals an exhibiting structure for thedisplay of flat articles that includes exhibition units that are piledone on top of the other, preferably in a base unit. The structureincludes at least one exhibition unit that can have a supporting device,such as a panel that has an exhibition removable element.

The British Patent GB 2 440 112 reveals a temporary exhibition shelf forproducts, that is comprised of a body, configured to promote a product,the body is built with folded cardboard, plastic or other similarmaterials, and a plurality of modular shelves that are reusable andready to receive new units of the product; the shelves are fixed in adetachable manner on the body, made of plastic and configured so thatthey can be reused with other configured bodies in order to promotedifferent products once the previous products have been removed from thebody.

Similarly, the American U.S. Pat. No. 4,785,944 reveals a display anddispensing device that includes a shelf made of cardboard that has arear wall and lateral walls that hang, provided with vertical spaces andlongitudinal spaces apart from each other that outline a pair of armsthat are projected towards the front, and that have a rail that outlinesthe upper borders and crossed pieces that stretch out the exhibitdevice, and the walls are hung on the extremes opposite to the frontextremes of the arms of each pair.

The American U.S. Pat. No. 5,458,411 reveals a unit of shelf made offolded cardboards that include a base element that has a rear panel,with lateral panels that stretch towards the front of the oppositeborders of the base element.

The American U.S. Pat. No. 6,068,140 reveals an exhibition unit that iscomprised of a frame and a plurality of trays that are set up in aremovable manner. The frame is built of one only cardboard piece and itincludes rear panels, lateral panels and an upper and a lower panel. Thelateral, the upper and the lower panels are foldable in a double wallconfiguration for greater strength and stability. The trays includehooks to secure the trays in the frame. The trays can be divided into aplurality of compartments.

None of the previously mentioned publications reveals a showcase thatcan be assembled and packed quickly, that is easy to put up and that canbe set up in different ways.

BRIEF DESCRIPTION OF THE INVENTION

The present invention releases a showcase for products in a point ofsale, which is comprised of a frame, in which at least a shelf is in arotational relationship with the lateral walls of the frame and at leastone rear support, which is also in a rotational relationship with thelateral walls of the mentioned frame.

The frame is generally provided with a rear wall and at least twolateral walls.

The shelves or racks rotate from a first position in a packed form to asecond position in an unpacked form, where in the second position theshelves are capable of bearing the products to be sold.

In order to rotate the shelves, at least one fastener is provided sothat it allows the rotation of the shelf in relation to the lateral wallof the frame.

The shelf is generally provided with a lower wall and at least twolateral walls. There is at least a hole in the lateral walls of theshelf, as well as a hole that is collinear with the previously mentionedhole on the lateral walls of the shelf on the lateral wall of the frame.The fastener is capable of holding the shelf in a rotational manner, sothat it fastens the shelf onto the frame and allows the rotation of theshelf in relation to the frame.

The hole in the lateral wall of the shelf is in an upper internalposition of the lateral wall of the shelf, where the internal part isproximate to the frame and where the external part is distant from theframe. The hole on the lateral wall of the frame, which is collinearwith the hole on the lateral wall of the shelf, is proximate to theexternal part of the lateral wall of the frame.

This way, it is possible to rotate the shelf upwards and inwards theframe for a packing position. To unpack the shelf, it has to be rotateddownwards and outwards the frame, where the lower interior corner of theshelf works as a stop limit in order to keep the shelf in a fixedunpacked position.

There is at least one shelf in the frame and the number of shelves islimited to the distance between the shelves and the height of theshowcase.

The rear support is held by the lateral wall of the frame. The rearsupport has at least one hole at the upper part of the rotation arms,where the hole can be collinear with the holes of the lateral walls ofthe shelf and of the frame respectively, or it can be collinear with asecond hole on the lateral wall of the frame. If it is collinear withthe other holes, the same fastener previously described is capable offastening the shelf and the rear support in a rotational relationship,in relation to the frame. If it is not collinear with the other holes, asecond fastener is provided and is capable of fastening the rear supportin a rotational relationship, in relation to the frame.

In a first embodiment, the frame has a hexahedral shape. In the interiorof the hexahedron, a spring or elastic mechanism is provided in order tostore mechanical energy so that it can provide automatically the productthat is being exhibited. The lower wall of the shelf bumps into thespring. The shelf is positioned in a movable manner within thehexahedron. Specifically, the shelf is set so that it can slide withinthe hexahedron, where the more weight the shelf that contains theproduct being exhibited has, the spring will be in a working position.When the weight of the shelf that contains the exhibited product isbeing removed, the spring will tend to go towards a resting positionpushing the shelf upwards.

In a second embodiment, a fastening system can be provided between theframe and the rear support. Specifically, the fastening system can befixed close to the intermediate part between the lower extreme part ofthe frame or of the rear support and the intermediate part of theframe's length or of the rear support. However, the fastening system canalso be fixed proximate to the lower extreme of the frame and of therear support. Optionally, the fastening system is located, on the onehand, close to the lower extreme part of the frame, and on the otherhand, close to the intermediate part between the lower extreme part ofthe frame or of the rear support and the intermediate part of theframe's length or of the rear support.

In this second embodiment, the fastening system is provided with atleast two more fasteners, as well as with two arms for each lateralextreme, a first arm coupled with the rear support and a second armcoupled with the lateral wall of the frame. Both fasteners allow therotation of the fastening system in relation to the frame and inrelation to the rear support. The arms are coupled with one another bymeans of a fastener that allows the rotation between the two arms. Thisway, when the showcase is being disassembled, the arms of the fasteningsystem do not occupy too much space and they are rotational in relationto the whole exhibiting system. Preferably, the fastener that couplesboth arms with one another, blocks the movement of the arms, reason forwhich the height, the position and the lower area that the showcaseoccupies varies depending on the position of the arms. The position ofthe arms can be the result of the weight that the showcase has, as wellas its height.

In a third embodiment, the showcase can have a double face for thesupply of products. This means, a second frame with shelves is providedinstead of the rear support. In this embodiment it is preferable to havea base and the fastening system described above. The base must have asimilar area as that of the shelves, and it is preferable when the basecan be in complete contact with the ground.

In an alternative of the third embodiment, the showcase can be folded byone of the two faces, and subsequently it can be folded up in such waythat the rear part rests super-imposed in relation to the front part andhanging by the upper part of the frame of a wall. In a secondalternative of the third embodiment, the showcase can be folded by oneof the two faces, and subsequently it can be folded up in such way thatthe rear part rests super-imposed in relation to the front part and thatthe showcase can be rotated so that the shelves remain in a downwardposition, then forming a table for the exhibition of products, where theshelves function as the legs of the table. In a third alternative of thethird embodiment, the base can be detached and be placed close to thejoint of the two faces. The showcase can be rotated to 180° from itsoriginal position and it can then be self-standing.

This way, an objective of the present invention is to provide a showcasethat can be easily assembled and packed.

Another object of the present invention is to provide a showcase thatcan contain a substantially heavy load of products, in combination withthe first objective.

Another object of the present invention is to provide a showcasesubstantially flexible as for its assembly and usefulness.

And yet another object of the present invention is a method for theassembly of the showcase mentioned above.

And one more object of the present invention is a method for the packingof the showcase.

DETAILED DESCRIPTION OF THE INVENTION The Shell of the Showcase

What follows implies, in general, what is related to figures from 1 to7. The present invention reveals a showcase 1 for products in a point ofsale. The showcase 1 generally consists of a frame 10 and a rear support20.

The frame 10 is composed of two lateral walls 11, 11′, a lower wall 12and optionally an upper wall 13. The lateral walls have at least twofaces, where a first face 14 is substantially perpendicular to a secondface 15. It is preferable that the vertex formed between both faces 14,15 is directed towards the exterior of the showcase 1, though the vertexbeing formed between both faces towards the interior of the showcase 1is not to be ruled out. Optionally, it can be provided that the lateralwalls have a tubular shape or an enlarged hexahedral shape. The lowerwall 12 can be composed of only one face, which is substantiallyperpendicular to the first face 14 and second face 15 of the lateralwall 11, 11″, even if it can have two faces or, it can have a tubularshape or an enlarged hexahedral shape.

The rear support is constituted by two arms 21, 21′, which are the meansof support opposite to the lateral walls 11, 11′ of the frame 10, alower joint 22 between the two arms 21, 21′ and optionally an upper prop25. The shape of the arms 21, 21′ can be formed with only one face 23,however, as it will be shown in one of the following modalities, it ispreferable that the form of these arms 21, 21′ and of the lower joint 22is similar to the form of the lateral walls 11, 11′ and the lower wall12 of the frame 10, that is, that the arms 21, 21′ are provided with afirst face 23 and with a second face 24, or that it has a tubular shapeor an enlarged hexahedral shape.

The frame 10 and the rear support 20 have at least a certain convergencepoint 19. At the upper part of the frame 10 as well as at the upper partof the rear support 20 there is a hole. However, this hole in the frame10 can be provided at an intermediate part. In order to put the frame 10together with the rear support 20, a hole must be positioned at theupper part of the frame 10, collinearly with the hole at the upper partof the rear support 20. A first fastener 60 fixes the frame 10 on therear support 20 through the collinear holes. The first fastener 60 musthave certain looseness what will allow the rotation of the rear support20 in relation to the frame 10. Preferably, the hole on the frame 10must be positioned at the upper or intermediate part of the frame 10,specifically at the upper or intermediate part of the second face 15 ofthe frame, and more specifically at the upper or intermediate part ofthe second face 15 of the frame, and close to the vertex formed betweenthe faces 14, 15 of the lateral walls 11, 11′. Preferably, the hole onthe rear support 20 must be located at the upper part of the rearsupport 20, specifically at the upper part of the arms 21, 21′, and morespecifically at the upper part of the arms 21, 21′ and close to the edgedistant from the vertex between the first face 23 and the second face 24of each arm 21, 21′.

Optionally, at least one fastening system 30 can be provided between theframe 10 and the rear support 20. The fastening system 30 is preferablypositioned close to the intermediate part between the lower extreme part26 of the frame 10 or of the rear support 20 and the intermediate part27 of the length L₂ of the frame 10 and the length L₁ of the rearsupport 20. Optionally, the fastening system 30 is placed close to thelower extreme part 26 of the frame. Optionally, the fastening system 30is located, on the one hand, close to the lower extreme part 26 of theframe 10 or of the rear support 20, and on the other hand, close to theintermediate part between the lower extreme part 26 of the frame 10 orof the rear support 20, and the intermediate part 27 of the lengths L₁,L₂ of the frame 10 or of the rear support 20. It is also possible toprovide a showcase 1 with at least two fastening systems 30 between theframe 10 and the rear support 20.

In the fastening system 30, at least a second fastener 61 and a thirdfastener 62 are provided, as well as two arms 31, 31′. A first arm 31 iscoupled with the rear support 20 and a second arm 31′ is coupled withthe lateral wall 11 of the frame 10, and more specifically with thesecond face 15 of the lateral wall 11 of the frame 10. The fasteners 61,62 make it possible for the fastening system 30 to rotate in relation tothe frame 10 and in relation to the rear support 20. Specifically, thesecond fastener 61 grips the rear support 20 and the first arm 31through a hole on the first arm 31, and there is a hole in the rearsupport 20 that is collinear with the hole of the first arm 31, wherethe second fastener 61 is positioned in a point slightly above inrelation to the center of the intersection point between the rearsupport 20 and the first arm 31. The third fastener 62 grips the frame10 and the second arm 31′ through a hole in the second arm 31′ and ahole in the frame 10 that is collinear with the hole in the second arm31′, where the third fastener 62 is positioned in a point slightly abovein relation to the center of the intersection point between the frame 10and the second arm 31′. Optionally, the second fastener 61 and the thirdfastener 62 can be dismissed, and the hole of the second arm 31′ can bemade to be collinear with a shared hole with a shelf 40, as will beexplained further ahead, reason for which the mentioned second and thirdfasteners 61, 62 would not be necessary. The arms 31, 31′ are coupledwith one another by means of a fourth fastener 63 that allows therotation between both arms 31, 31′. The third fastener is positionedpreferably centered in relation to the center of the convergence pointbetween the first arm 31 and the second arm 31′. This way, when theshowcase 1 is disassembled, the arms 31, 31′ of the fastening system 30do not occupy a major space and are rotational in relation to all theexhibiting system (showcase) 1. Preferably, the fourth fastener 63 thatcouples the arms 31, 13′ with one another, blocks the movement of thearms 31, 31′, reason for which the height, the position and the lowerarea that the showcase 1 occupies varies depending on the position ofthe arms 31, 31′. The position of the arms 31, 31′ can be the result ofthe weight of the showcase 1, as well as its height.

The length of the arms 31, 31′ can vary from one to the other dependingon the configuration between the arms 31, 31′, the frame 10 and the rearsupport 20. For example, if the fastening system 30 is positioned closeto the intermediate part between the lower extreme part 26 of the frame10 or of the rear support 20 and the intermediate part 27 of the lengthof the frame 10 or of the rear support 20, or as well if the fasteningsystem 30 is positioned close to the lower extreme part 26 of the frameand of the rear support 20, the arms 31, 31′ preferably should have thesame length. If the fastening system 30 is positioned, on the one hand,close to the lower extreme part 26 of the frame, and on the other hand,close to the intermediate part between the lower extreme part 26 of theframe 10 or of the rear support 20 and the intermediate part 27 of thelength of the frame 10 or of the rear support 20, it is preferable thatthe part close to the lower extreme 26 of the frame 10 has a greaterlength than that of the part close to the intermediate part between thelower extreme part 26 of the frame 10 or of the rear support 20 and theintermediate part 27 of the length of the frame 10 or of the rearsupport 20, in such way that when the showcase 1 is rotated towards acollapsing or packing position, the fastening system 30 does not stickout in relation to the rest of the exhibiting system (showcase) 1. Thislast configuration is plausible for when the showcase 1 has one side forload and hence a greater sustaining capacity of a certain side isrequired. This last configuration is also plausible for when theshowcase 1 has two sides for load, and where a greater sustainingcapacity of one of the two determined sides is required.

Fastened onto the lateral wall 11 of the frame 10, there are shelves andracks 40 that rotate from a first position in a folded or packed form,to a second position in an unfolded or unpacked form, where in thesecond position, the shelves 40 have the capacity to bear products to besold. The shelves 40 are usually comprised of at least lateral walls 41,41′ and a front joint 45 between the lateral walls 41, 41′. The lateralwalls 41 have at least one face 43, however, a lower wall can beprovided with a first face 42 that is substantially perpendicular to theface 43 of the lateral wall 41. It is preferable that the vertex formedbetween both faces 42, 43 is located at the upper part of the showcase1, even though the possibility of a vertex between both faces formedtowards the lower part of the showcase 1 is not to be ruled out.Optionally, lateral walls 41 can be provided with a tubular shape orwith an enlarged hexahedral shape. The lower wall formed by the firstface 42 can be comprised of a constant and uniform face that covers allthe surface of the shelf 40, functioning as a sort of plank where theproducts to be sold are set up.

In order to rotate the shelves 40, at least one fastener 64 is provided,it is capable of fastening the shelve onto the lateral wall 11 of theframe 10, and it can allow the rotation of the shelf 40 in relation tothe lateral wall 11 of the frame 10.

At least one hole is provided in each of the lateral walls 11 of theframe 10, where the hole of the lateral wall 11 is collinear with thehole on the lateral wall 11′, in a way that the fasteners 64 in each ofthe lateral walls 11, 11′ are at the same height, and in a way as wellthat the shelf 40 remains at a constant and uniform height on its sides,in relation to the frame 10.

In the same way, a hole is provided in each of the lateral walls 41 ofthe shelf, where the hole of the lateral wall 41 is collinear with thehole of the lateral wall 41′, so that when the shelf 40 is set up withthe fasteners 64 onto the frame 10, the shelf 40 remains at a constantand uniform height on its lateral sides 41, 41′ in relation to the frame10. When setting up the shelf 40 into the frame 10, the holes on thelateral wall 41 of the shelf 40 must be uniform with the holes on thelateral wall 11 of the frame, and the holes on the lateral wall 41′ ofthe shelf 40 must be uniform with the holes on the lateral wall 11′ onthe frame.

The fasteners 64 are capable of holding the shelf 40 in a rotationalmanner, in such way that shelf 40 is fastened onto the frame 10 and thatit allows the shelf 40 to rotate in relation to the frame 10.Specifically, a fastener 64 is required for the lateral wall 41 of theshelf 40 and the lateral wall 11 of the frame 10, and another fastener64′ for the lateral wall 41′ the shelf 40 and the lateral wall 11′ ofthe frame 10. Equally, it is preferable that the fasteners 64 have thecapacity to fasten the shelf 40 in a loosening manner, so that eachshowcase 1 can be provided independently from the shelves 40, and sothat the shelves 40 may be set up in situ.

The hole in each of the lateral walls 41, 41′ of the shelf 40 is locatedat an internal upper position of the lateral wall 41, 41′ of the shelf40, where the internal part is the most proximate to the frame 10 andwhere the external part is the most distant from the frame 10. The holeof the lateral wall 11, 11′ of the frame, same that, when the shelf 40is set up with the frame 10 and is collinear with the hole of thelateral wall 41, 41′ of the shelf 40, is located proximate to theexternal part of the lateral wall 11 of the frame 10. However, a hole onthe lateral wall 11, 11′ of the frame can be provided, being centralaccordingly to the width of the lateral wall 11 of the frame 10.

This way, the rotation of the shelve 40 is possible upwards and towardsthe interior of the frame 10 for a packing position. To unpack the shelf40, it is rotated downwards and towards the exterior of the frame 10,where the lower interior corner of the shelf 40 works as a stop limit inorder to support the shelf 40 in a fixed unpacked position.

Optionally, a base 50 can be provided, this one is capable of holding onto the frame 10 at the lower or upper part of the frame 10. This is, itis required that the base 50 be a hexahedron with base and top thatallow the entrance of the lateral walls 11, 11′ of the frame 10. Amongthe hexahedrons a rhombohedron is preferable and even more preferable isa truncated rhombohedron, so that, among other functions, it can becoupled with the way the lateral walls 11, 11′ of the frame 10 fall andto provide a better coupling of the showcase 1 with the ground.

Optionally, an advertising panel or overhang 3 on the convergence point19 between the frame 10 and the rear support 20 can be added.

Optionally, a tilted prop 4 between the interior and exterior corners ofthe rear support 20 or between the interior corners of the frame 10 canbe provided. The prop 4 is provided in order give the showcase 1 greaterrigidity.

First Embodiment

Reference in this section will be made to figures from 8 to 15.

In a first embodiment, the rear support 20 has a convergence point 19with the frame 10 in a part slightly above the intermediate part of thelength of the frame 10, reason for which the rotation point of the rearsupport 20 in relation to the frame 10 is precisely at this convergencepoint 19.

In this first embodiment, a more complete frame 10 is shown.Specifically, it shows a frame that has a rear wall 16 that does notallow visibility to the user towards the rear support 20. Specifically,in this case, the first face 14 has been dismissed from the lateral wall11 and it has been substituted completely by a rear wall 16. Hence, whenthe shelf 40 rotates, the upper part of the lateral walls 41 of theshelf 40 will bump, when the showcase is moved to the folded position,into the mentioned rear wall 16. When the shelf rotates, the lowerinternal corner of the shelf will bump, when the showcase is moved to anunfolding position, into the mentioned rear wall 16.

In order to collapse the showcase 1 in this first embodiment, initiallythe shelves 40 must be rotated upwards and towards the interior of theframe 10. Subsequently, the rear support 20 is rotated towards the frame10. Subsequently, the showcase 1 is uncased and then the showcase isenveloped.

In order to set up the showcase 1, this one has to be unfolded, and theclothing or casings 55 are then separated from the showcase. The rearsupport 20 is rotated in opposite direction from the frame 10. Each ofthe shelves 40 is rotated downwards and outwards in relation to theframe 10, until the lower interior corner of the shelf 40 bumps into therear wall 16 or into the first face 14 of the lateral wall 11. Finally,the showcase 1 is cased.

Second Embodiment

Reference will be made to figures from 16 to 20

In a second embodiment, the frame 10 has a hexahedral shape. Specially,a geometric figure such as a cuboid is preferred; however, a cube or arhombohedron can also be used for the frame 10.

In the interior of the hexahedron, a spring 2 or an elastic mechanism isprovided, used to store the mechanical energy and so to provide theproduct that is being exhibited automatically. The lower wall of theshelf bumps into the spring.

In the interior of the frame 10, the shelf 40 is placed, and it isplaced in a movable manner, specifically slidable within the frame 10.

Between the shelf 40 and the lower part of the frame 10 or the floor,there is a spring 2 or an elastic mechanism used to save mechanicalenergy. The spring 2 is there so that it can push the shelf 40 upwards.Therefore, the more weight the shelf 40 has, the spring 2 will be in aworking position and the shelf 40 will be in a lower position inrelation to the frame 10. While the weight is being removed from theshelf 40, the spring 2 will tend to go towards a resting position,pushing the shelf upwards in relation to the frame 10, just as is shownwith an arrow in FIG. 18 or 20.

In FIG. 16 an alternative is shown, where a casing 55 is provided at thelower external part, in order to cover the spring 2 and form a kind ofbase 50, and this way form a window 51 towards the interior of theshowcase 1, and specifically towards the products that are beingexhibited.

A way of holding the casing 55 together with the shelf 40 can beprovided. For example, the casing 55 can be fastened onto the shelf 40by means of a fastener, with the finality of making it possible for thecasing to also slide according to the filling of the shelf 40. In thisembodiment, it is possible to make the lower part of the casing of asoft and collapsible material, with the object of, if the shelf is witha maximum load, the casing 55 does not obstruct the stretching of thespring 2 upwards into the working position.

As another embodiment, a window 5 can be provided in order to measurethe existing level of product within the frame 10.

The products are piled one on top of the other, so that the shelf 40 isbeing pushed downwards, and therefore, the window 5 measures the amountof product within the frame 10.

The same way as in the previous embodiment, it is preferable to have arear wall 16; however, the first face 43 of the shelf 40 can function asa rear wall 16.

Third Embodiment

Reference will be made to figures from 21 to 26.

In the present embodiment, the rear support 20 is comprised of two arms21, 21′ and a lower joint with a similar shape as that of the lateralwalls 11, 11′ and of the lower wall 12 of the frame 10. Specifically,the rear support 20 is composed of two arms 21, 21′, a lower joint 22and optionally an upper wall. The lateral walls 21, 21′ have at leasttwo faces, where a first face 23 is substantially perpendicular to thesecond face 24. It is preferable that the vertex formed between bothfaces 23, 24 is towards the exterior of the showcase 1, though that thevertex between both faces 23, 24 is formed towards the interior of theshowcase 1 is not to be ruled out, so that these faces may be coupleddirectly with the rear part of the frame 10. Optionally, it is possiblethat the lateral arms 21, 21′ have a tubular shape or an elongatedhexahedral shape. The lower joint 22 can be comprised of only one face,which is substantially perpendicular to the first face 23 and the secondface 24 of the lateral wall 21, 21′.

Fastened onto the lateral arms 21, 21′ of the rear support 20, are theshelves or racks 40 that rotate from a first position in a folded orpacked form, to a second position in an unfolded or unpacked form, wherein the second position, the shelves 40 are capable of sustainingproducts that will be sold. The lateral walls 41 of the shelves 40 haveat least one face 43; however, there can be a lower wall 44 with a firstface 42 that is substantially perpendicular to the second face 43 of thelateral wall 41. Optionally, the lateral walls can have a tubular shapeor an elongated hexahedral shape. The lower wall 44 can be comprised ofa constant and uniform face that covers all the surface of the shelf 40,functioning as a plank where the products to be sold are set up.

In order to rotate the shelves 40, at least one fastener is provided, itis capable of fastening the shelf 40 onto the lateral arms 21, 21′ ofthe rear support 20 and it also allows the rotation of the shelf 40 inrelation to the lateral arms 21, 21′ of the rear support 20.

At least one hole is provided in each of the arms 21, 21′ of the rearsupport 20, where the hole of the arm 21 is collinear with the hole ofthe arm 21′, in such way that the fasteners in each of the arms 21, 21′are at the same height, and in such manner that the shelf 40 remains ata constant and uniform height of its sides in relation to the rearsupport 20.

In the same way, a hole is provided on each of the lateral walls 41 ofthe shelf, where the hole on the lateral wall 41 is collinear with thehole on the lateral wall 41′, in such way that when the shelf 40 is setup with the fasteners onto the rear support 20, the shelf 40 remains ata constant and uniform height of its lateral sides 41, 41′ in relationto the rear support 20. When setting up the shelf 40 on the rear support20, the holes on the lateral wall 41 of the shelf 40 must remain uniformwith the holes on the arm 21 of the rear support 20, and the holes onthe lateral wall 41′ of the shelf 40 must be uniform with the holes onthe arm 21′ of the rear support 20.

The fasteners are capable of holding the shelf 40 in a rotationalmanner, in such way that it fastens the shelf 40 onto the rear support20 and that at the same time it allows the shelf 40 to rotate inrelation to the rear support 20. Specifically, a first fastener isrequired for the lateral wall 41 and for the arm 21, and a secondfastener for the lateral wall 41′ and the arm 21′. In the same way, itis preferable that the fasteners are capable of holding the shelf 40 ina loosening manner, so that each showcase 1 can be providedindependently from the shelves 40, so that the shelves 40 can be set upin situ.

The hole of the arms 21, 21′ of the rear support 20, same that, when theshelf 40 is set up with the rear support 20 it is collinear with thehole of the lateral wall 41, 41′ of the shelf 40, is situated proximateto the external part of the arm 21 of the rear support 20. However, thehole of the arm 21, 21′ of the rear support can be central in relationto the width of the arm 21, 21′ of the rear support 20.

This way, the rotation of the shelf 40 upwards and towards the interiorof the rear support 20 is possible to achieve when in a packingposition. To unpack the shelf 40, it has to be rotated downwards andtowards the exterior of the rear support 20.

The third embodiment can be combined with the second embodiment. Thisis, it is possible that both the frame 10 and the rear support 20 havehexahedral shapes.

Other Modalities

In the figures of this third and last embodiment, several sub-modalitiesare shown that can be applied to all the modalities of the presentinvention, and more specifically, speaking about FIGS. 21, 22, 23, 24,25, 26, 27 and 28.

In the embodiment of FIG. 21 what is shown is how the fastening system30 is located proximate to the lower extreme part 26 of the frame 10 andof the rear support 20.

In FIG. 22, while being folded, the showcase 1 can hang on a verticalwall, due to the fact that the second face 15 of the upper wall 13 ofthe frame 10, works as a hanging device for the showcase 1. This means,that because the vertex between the first face 14 and the second face 15of the frame 11 is formed, usually towards the exterior of the showcase1, the showcase 1 can be hung from the upper wall 13 of the frame,specifically from the second face 15 of the upper wall 13 of the frame10. And so, the only parts projecting out are the rear support 20 andall its respective walls and the shelves 40 attached to the rear support20.

In figures from 23 to 25, the shelves 40 can be removed, with theexception of the extreme shelves 40. Additionally, a shelf 40 has beenrotated with respect to the other one, with the finality of having thesetwo rotating in opposite directions. Besides, a rear wall 16 has beenopted for instead of the first face 14. This way, when the shelves areunfolded and the showcase 1 is rotated so that the shelves 40 are facingdownwards, it so happens that the showcase 1 can have the form of atable, where the products can be exhibited on top of the rear wall 16.The shelves 40 work as the table's legs.

FIGS. 27 and 28 show how the fastening system 30 can be a multi-positionsystem. This means, as it was mentioned before, that the third fastenerthat couples both arms 31, 31′ with one another, blocks the movement ofthe arms 31, 31′, reason for which the height, the position and thelower occupation area of the showcase 1 is adjustable depending on theposition of the arms 31, 31′.

Finally, FIG. 26 is adaptable only to the third embodiment and to thecombination between the second and third modalities. In this case, theshowcase 1 is reversed 180° in relation to its original position. Thebase 50 is reversed and put on the place of the overhang 3. Thisreversed base 50 will give stability to the showcase 1. Additionally,the shelves 40 are rotated 180° in relation to their initial position.If the arms 31, 31′ of the fastening system 30 are at 180° from eachother, the shelves are tilted downwards. If the arms 31, 31′ of thefastening system are between 45° and 135°, the shelves have no tilt. Thefastening system 30 and the area between the frame 10 and the rearsupport 20 can be covered with the casing 55.
